IMPROVEMENT IN REFRIGERATOAR-CARS.

Specification forming part of Letters Patent No.` 131,722, dated September 24, 1872.

To all whom it may concern:

Be it known that I, RICHARD J. TUNs'rALL, of St. Louis, in the county of St. Louis and State of Missouri, have made certain new and useful Improvements in Refri gerator-Oars, Snc. 5 and Ido hereby declare that the following is a full and true description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

This invention relates to refrigerator-cars for the preservation and transportation of meats and provisions, so as to deliver the same to the markets in a sound and healthy condition. The nature of this invention chiefly consists in providing the top of refrigerator-cars with a V-shaped ice-receptacle; also to certain detail construction of parts, all of which will now To enable those herein skilled to make and usem y said improvements, I will now more fully describe the same, referring to thfe aceompan ying- Figure 1 as alon gitudinal sectional elevation 5 to Fig. 2 as a transverse sectional elevation.

The car Ais constructed and supported upon trucks, as ordinary. On top the car is provided with suitable doors A for charging the icereceptacle with ice, the sides of the car being provided withdoors B B for packing pur` poses. The car'A, also its doors, are packed or lled, as usual, with suitable non-conductin g materialpthe interior L"of the car f being lined with galvanized sheet metal. Each of the top and side doors have their elosin g edges tted with rubber Weather-strips to form an air-tight iit. Inside the car A and attached to the top thereof by its` flanges c is properly secured a V-shaped metal receptacle or trough, C, as inrthrough which it is charged with ice.

dicated in Figs. l and 2p. The arrangement of the V-receptacle C is made to extend the length of the car in line with the top doors A', The said V ice-receptacle is made proportionate to theamount of space to be cooled, the object being to derive a refrigeration process or such 'a degree of temperature not below freezingpoint yet still below the fermentation-point. At each opposite ends are connected to the V- receptacle C drain-pipes D 'D, arranged to pass vertically through the car, (see gures,) and the waste from the ice-chamber C being facilitated in its escape by the gutter form of the bottom of said ice-chamber G. to secure the side doors B B when closed, a rod, E, is arranged longitudinallyor transversely, its screw threaded ends passing through the latch-bars e, a nut or screw-cap, c', securing the closed doors, as shown in Fig. 2. The interior of the car is provided with hooks and stays to hang provisions. The V- shaped receptacle is adapted for the ceiling of packing-houses or chambers for refrigeration purposes. y

Having thus fully described my said invention7 what I claim isrEheY car A, provided with a V-shaped icereceptacle attached to its ceiling, top doors A and side doors B B', secured by screw-rod E, the whole being arranged substantially as described fer the purpose set forth.

In testimony of said invention I have. hereunto set my hand.
